Now we're talking! Ever tried this? Hi, Stick this in your rpt.conf... outstreamcmd=/bin/sh,-c,/usr/local/bin/lame --preset cbr 16 -r -m m -s 8 --bitwidth 16 - - | /usr/local/bin/ezstream -c /etc/ezstream.xml You will need lame and ezstream obviously...

All,
Has anyone come up with an elegant solution to snag a copy of the audio streams to and from a repeater in order to send it to Radio Reference without requiring an additional sound card and/or interface? On Jun 16, 2013 11:00 AM, <app_rpt-users-request@ohnosec.org> wrote:

I expect it is possible with Alsa, but honestly my brain turns to mush when reading through their documentation.

Thanks guys!
Buddy and Chris both helped me out and it seems to be working fine. Now to work though the learning curve...

Greetings All,
While thinking of a way I can turn my node into a portable allstar node, it has been discovered the computer I'm using, generates RFI/EMI over the DC power connection.
The setup is as follows presently, which has zero *known* EMI/RFI issues. The radio is powered with an older linear 3A regulated power supply, which a parallel connection to a 12V 18Ah battery. All leads are kept short, under two feet. The radio is kept on 5W.
The computer has a 12Vdc connection, and it's presently using an ac/dc SMPS, one that can be bought on eBay for about $10.
Both of these are plugged into the same outlet strip, and as stated, zero discovered EMI/RFI issues.
The radio audio connections to the computer have the center conductors isolated with a 10nF cap.
Just as soon as I decide to power the computer from the battery, the radio has noise across every tunable frequency. Even if I disconnect the radio completely from the node, there is noise on the radio. From what is apparent to me, the noise is coming from the computers internal power supply section, riding the power wires back to the battery, and then to the radio.
I see there are plenty of EMI/RFI filters I can purchase. However, I'd like to maintain the Amateur Radio Spirit of creation for this case, so I'd like some pointers on what I should test for, and construct some EMI/RFI filters.
I have seen there are common mode and differential mode chokes filters, and some filters have both kinds of chokes. I'm not really sure the difference, besides the way the components are installed in the circuit.
If you find it better to talk in person, contact me via allstar or look for my phone number on the internet.

Perhaps a:
RadioShack? Snap-Together Ferrite Choke Core (273-105) might do the trick, or maybe a:
Snap Choke Core (273-069)
or something similar.
